Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/skill-name-must-equal-the-parent-folder-name-of-skill-md-lowercase-hyphenated-griddynamics/— the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.
Quick install (SKILL.md only)Sign up to copy - Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

When Claude uses it
GENERIC form: To <verb> <what it does + when/why; dense keywords>. CRITICAL/guardrail form: 'Rosetta CRITICAL MUST skill. MUST activate when <condition>'. Budget: all skills share ~1K tokens — keep ≤ ~25 tokens and dense; over-long is ignored the same as terse, keyword-dense descriptions trigger best. EXCEPTION: disable-model-invocation:true => this description is actually user friendly.
What this skill does
[ONLY FOR TEMPLATE EXECUTOR: imperative bullet points, shorter lines, distinguish references to repository files vs instructions; skill/subagent names will be in context already, so just reference it. the rest of instruction folder files: rules/templates/workflows/assets/subfolders of skill/etc must be ACQUIRE'd / SEARCH'd / LIST'd to be used]
